To all whom 2'25 may concern:

Be it known that if, Jnrrn Loner. XVARD, a citizen of the United States, and aresident of Hutchinson, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Gearing, of which the following 1s a specification.

The present .invention relates to gearing, and more particularly to an improved variable speed and .reversegearing.

The object of the invention is to provide gearing of this character which embodies the desirable features of 'both selective and planetary types and which is especially adapted for use with that class ofv motor vehicles requiring only two speeds forward and a reverse.

and simple andinexpensive to manufacture.

Other objects and advantages reside in certain novel features of construction combination and arrangement of parts which will "be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to'the accompanying drawings forming part, -of' this specification, and in which:

Figure l is a side. elevation of my improvement, the housingbeing shown in section and parts being broken away for the sake of illustration;

Fig. 2 is a side elevation, showing-the gearing in reverse;

Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2;

Fig. 4 is an elevational view, the gearing being'shown in low; r Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 4;;

Fig. 6 is a vertical longitudinal sectional view on line showing the gearing in high.

Fig. 7 is a'sectional view on line 7 7 of Fig.4. I

Referring to the drawings, the housing 10 is preferably constructed in two sections, .11 and 12, respectivelyythe meeting ends of the sections beingv secured together in any suitable manner. vided with a bearing 13 and the sect-ion -12 s provided witha bearing 14.

drivenshaft- .15'}isprovided with a unlversal joint 16, and the end of the driven 'lihe section 11 is .pro-

shaft indicated at 13', is journaled the 1 'bearing'lii. This end of the shaftis provided with an axial bore 18-eXtending for a SHlOStfl-Ilfiltl distance of the shaft, and the extreme :end of the shaft hasfthe portion surrounding the axial bore formed to constitute a ratchet clutch member 19. A drive shaft 20 is slidable and rota-tably mounted in the bearing 14. The drive shaft-carries a collar2l, with which the yoke 22 of aselector orxcontrol leveroperates' to impart sliding movement to the shaft and to there;

by controlthe gearing as will hereinafter appear. The 'innerend. of-the drive shaft indicated'at 24; is slidably and rotatably mounted in the axialbore 18 0f the driven shaft and the inner end of the drive shaft carries aratchet clutch member '25 which is fixed tothe shaft and which is adapted in the extreme inner position ofythe drive shaft to engage the clutch member 19 ofv the driven shaft and thereby directly connect the drive shaft to the driven shaft-and transmit'the motionof the drive-shaft unchanged tothe V driven shaft;

Drive pinions,preferably a pair indinot only constrained to rotate therewith but-they are also held against longitudinal displacement .onthe drive shaft.

A frame or carrier indicated generally at 29, is loosely' mounted on; the drive shaft so as to .be freely rotatable with respect to the drive shaftgbut to be held against longitudinal motion with respectto the drive shaft.

y- 1 y ding-motion that: it

imparted to the driveshafti's partaken of by the frame or carrier, whereas therotary motion of the 'd-rive sliaft never directly communicated to the carrier; The carrier The key '28 serves to secure the 'ccomprisesapair of spaced circular plates 30 and 31, which are provided with hubs 30 and 31, respectively. As shown in Fig. 6, the hub 31 of the right-hand plate 31 is supported directly by the drive shaft, whereas the hub 30 of the left-hand plate 30 is supported on the clutch member 25. The inner faces of the plates 30 and 31 abut against the outerfaces of the drive pinions 26 and 27, respectively, so that the carrier embraces the drive pinions. Spacing elements 33 are provided to maintain the plates in spaced relation. shafts 34 are extended between the plates and have their ends journaled therein.

A plurality of sets of gearing are arranged upon the carrier. These sets of gearing include a reverse gearing and in the preferred form of my invention only one other set-low speed gearing, but it is to be understood that additional sets of gearing to provide for additional variations in speed may be included, if desired. As seen in Fig. 3, he reverse gearing comprises a pinion 35, in meshwith the drive pinion 26 and a second pinion 36 which is in mesh with the pinion 35 and which may be meshed or engaged with an internal gear to be hereinafter fully described. The low speed gearing as seen especially in Fig. 5 comprises a single pinion 37' which is in mesh with the drive pinion 27 and which maybe meshed or engaged with the internal gear to be hereinafter fully described. Each of the pinions 35., 36 and 37 are mounted upon one ofthe shafts 34, which are positioned tocorrespond with the arrangement of the pinions and these pinions are further provided with a hub 38, which extends to the opposite plate and thereby to maintain the respective pinion against displacement from mesh with its respective drive pinion. 1

An internal gear 39 is preferably integrally formed on 'the housing but it mav if desired be separated and be securcdto the housing by any suitable means. The internal gear is adapted to engage or mesh with either the pinion 36 or the pinion 37 or to be out of mesh with both of these pinions. Means are provided for communicating; or transmitting motion of the carrier to the driven shaft. This means preferably coinprises a sleeve 40 secured to the plate 30. preferably by being formed integral ther with. The sleeve 40 is provided with a-plurality of longitudinally extending slots. preferably four in number, which consti tute kev-wa vs 41 and which receivelreys 42 rigidly formed on the driven shaft 15. Bv this arrangement the carrier is free to move longitudinally of the drive shaft but any rotary movement of thecarrier is imparted to the driven shaft. In operation it willbe seen that the gearmg is controlled by the lever or selector 23 which imparts a sliding motion to the drive A plurality of short neonate shaft 20. In theposition of the parts shown in Fig. 1, the driven shaft is disconnected from the drive shaft and no motion of the drive shaft would be communicated to the driven shaft. If it is desired to communicate motion to-the driven shaft the lever .3 would be shifted to slide the pinion 37 into engagement with the internal gear 89.

When it is desired to shift the gear into high, the controlling lever is actuated to slide the drive shaftQO farther to theleft until tie clutch member 25 fixed to the drive shaft engages the clutch member 19 on the driven shaft. in this position the drive shaft is directly connected to the driven shaft, and the motion of the drive shaft is communicated unchanged to the driven shaft. At this time both pinions 36 and 37 are out of engagement or mesh with the in- 1 ternal gear 39, as shown in Fig. 6. If it is desired to reverse the gearing the controlling lever 23 is actuated to slide the drive shaft 20 until the pinion 36 is engaged with the internal gear, as seen in Figs. 2' and 3.

in. this arrangement motion of the drive pinion 26 is communicated to the pinion 35 which in turn communicates its motion to the pinion 36. The pinion 36 being in. mesh with the internal gear 39 rolls on the-internal gear 39 and carries with it the frame or carrier, the rotation of which is however reversed with respect tothe motion of the drive shaft. This motion of the carrier is transmitted by the sleeve and key to the driven shaft. The neutral position is preferablv as seen in Fig. 1. V
